Hey, man, we can agree to disagree. OP cannot go wrong buying an SSD in this situation, IMO.
My last project was 50 devices on 30 tracks, which is my limit with my i3 which includes a lot of automation (70+ lanes); all 50 devices not playing at the same time, either. Before I got an SSD and max RAM on this i3 laptop my device count was more like 30 tops and always 17 mixer channels was the max. I have to steer away from Pulverizer and Combinators...too many Echos or Alligators can bring things to a halt too. I only use Combinators to save device groupings and their routings and then uncombine when I am composing. very occasionally I will use a few Combinators, but no more than 4. The main difference I have noticed is being able to have more SSL mixer channels and more automation that I could have before. I can't verify that claim though....it might have just been the set up of those songs.
The noiselessness and lower running temps are critical for me, too, like I said before...and a dealbreaker.
As far as I have seen, computer prices have gone up since last month's Coffee Lake non-launch. I want to be able to be free to throw anything at my DAW work, so it is waaaay beyond time for me. I have a windfall coming in soon, so I plan on going dual Xeon. Until that money hits the bank, I have to keep using what I have. I feel like I can relate to ionly's situation since our laptops are pretty similar spec.
